Patented Sept. 1I., 1951 UNITED STATE-s PATENT oFFIcE 1 FLANGED NU'i.`ASSEMBLYy l Philip D. Becker, Hingham, Mass., United-Carr FastenerCorporation, Cambridge, Mass., a corporation of Massachusetts.Application April 19, 1949, 's'ii No. Vvsa'ii'i 1 .Y This inventionrelates generally to nut assemblies, and. has particularreference to anut assembly adapted to be assembled in a structural member to enablethemmember to be readily fastened to a similar' member.

In the, constriifaincin of Vcertain parts of packcrates andsimilamdevies, it has been found economical touassemble the variousparts with huis @hd bolisigellow the. Crate wy be disas- Seinbledwithoutruamago tothe individual parts so that theyv maybe reused a greatnumber of times'. To accomplish this, a flanged nut is cominnly providedon one of two members to be joined, which has an internally threadedshank seated in one end of an opening through the member, and a flangedisposed about the shank and seated against the outer surface of themember. The flanged nut is adapted to engage a bolt inserted through theother member and into the opposite end of the opening to retain themembers in assembly. During assembly of the members, it is frequentlynecessary to hammer the bolt through the openings7 and as a result the:flanged nut is often knocked out of the opening, or so tilted that itis impossible to screw the bolt into the nut.

The object of ythe invention is to provide a nut assembly for use instructural members to enable the members to be readily assembled anddisassembled without damage to the members.

A further object of the invention is to provide a nut assembly which isadapted to be permanently assembled in structural members such as areused in shipping crates and similar devices.

A still further object of the invention is to provide a flanged nutassembly for use on joining Wooden structural members, Which has meansfor guiding a bolt into engagement with a threaded portion of the nut.

Other objects of the invention will, in part, be obvious, and will, inpart, appear hereinafter. For a fuller understanding of the nature andobjects of the invention, reference should be had to the followingdetailed description, taken in conjunction with the accompanyingdrawing, in which:

VReferringt'o `the.` ng', =there is illustrated a out assembly.ptedforassembly in am 'opening I2 through a structural member I4. Thenut assembly I0 comprises a hollow tubular member I6, which in thepreferred form has outwardly turned split end portions I8 at one endthereof, and a flanged nut 20 held in assembly with the tubular memberby means of a retaining member 22. The hollow tubular member ispreferably formed by rolling a piece of sheet metal into `the form of acylinder, and is of sufficient length to extend completely through themember I4. Ihe anged nut comprises a hollow internally threaded shank24, and a iiange 26 disposed about the shank at one end thereof. Theshank 24 is assembled in the end of the tubular member so that theflange 26 is seated against the outwardly turned split end portions I8.To Aprevent appreciable rotation of the nut relative to the tubularmember, a number of projections 28 are provided on the flange, whichproject outwardly between the split end portions. The retaining member22 comprises a disc portion 30, having an opening 32 disposed centrallytherein to receive the tubular member, and a peripheral flange engagingportion 34. The retaining member 22 is mounted on the tubular member I6with the disc portion 30 seated against the Voutwardly turned split endportions I8, and the peripheral flange engaging portion 34 is curledover the outer edge of the flange to retain the flanged nut and thetubular member in assembly.

To provide means for permanently retaining the nut assembly in theopening in the structural member, the opposite end of the tubular memberis slotted longitudinally to form engaging A portions 36, which areadapted to be bent out- 40, which is disposed through an opening 42 inthe member 38, is inserted into the tubular member I6 for engagementwith the threaded shank 24, whereby tightening of the bolt in the Shankcauses the members I4 and 38 to be drawn securely together. Ashereinbefore described, it is frequently necessary to hammer the boltinto the openings during assembly of the members. However, since the nutis securely held in the opening by the engaging members 36, the nutcannot be knocked out of the opening, and the tubular member providessupport for the shank to prevent appreciable tilting or bending of theshank during such hammering. The tubular member also serves as a guidefor the end of the bolt to facilitate engagement of the bolt with theshank.

Although in the preferred form of the device the tubular member isprovided with split end portions for engagement by the retaining member,it Will be understood that a continuous peripheral ange may be used insome cases.

Since certain other modications maybe made in the device of theinvention, it is intended that al1 matter contained herein beinterpreted in an illustrative, and not in a limiting sense.

I clam: y

A nut assembly forl use with an apertured support, said nut assemblycomprising an elongated hollow tubular member adapted to extend througha support aperture and having outwardly turned split end portionsat oneend thereof, and split end portions at the other end adapted to beturned outwardly to engage thev support after the sleeve 4 is insertedthrough the aperture thereof, a anged nut comprising a hollow shank ofless length than the tubular member disposed in one end thereof andhaving an outwardly anged end portion seated against said outwardlyturned split end portions, said hollow shank having threads therein forengaging a bolt, said flanged end portion having raised portions thereondisposed between said split end portions to prevent appreciable rotationof the ilanged nut relative to the tubular member, and a retainingmember seated against the split end portions, said retaining memberhaving an outer edge portion curled over the outer edge of said flangedend portion to retain the flanged nut and tubular member in assembly.
